I only have the one HDMI output on the Virgin box.


There's bound to be a way of doing it - but have you considered that many
modern TVs have a sound delay in them to bring the sound into sync with
the display? So taking the sound off before the TV removes this. The
phonos on the TV designed to feed an external sound system include this
delay.

Good point.

Modern A/V receivers with HDMI I/O generally have an adjustable delay for
addressing this issue.

My HDTV's *only* output of any kind other than the picture is digital coax
(stereo, not multichannel), which does indeed have the proper amount of
delay for use with a standard DAC.

If I wanted multichannel, then I'd have to use one of the outputs of the
cable box. I've tested some of them and they all cause lip synch problems
unless additional delay is applied.

An AV amplifier would have an adjustable delay feature to bring the sound
into time-alignment with the picture. If the OP wants multi-channel sound
then this is his best option, if he only wants 2 channel stereo then using
the digital audio output from the TV will do the job for a lot less dosh.

I've heard that A/V amplifiers exist, but most people on this side of the
pond save a lot of money by going the receiver route. On Black Friday I saw
a 100 wpc multichannel receiver for under $100. The ad didn't give much
but brand and channel count. For sure, I saw 7.1 channels and HDMI for
under $200.

A receiver is just an amplifier with a radio tuner in it.

Of course, but around here, a given level of power and performance is
usually cheaper with the tuner thrown in than without it. Something about
sales volumes...

And it's the same around here, but in the context of this thread the term
"AV Amplifier" includes "AV receiver" since the later is simply the former
with an irrelevant tuner included. I didn't see the need to add "or AV
receiver" to my original post. But I do now! (some pedant is bound to make
an issue of an irrelevance).

Talking about sales volumes, have you noticed that virtually all AV
amplifiers (receivers!) are one-box efforts? If you want to keep the power
amps physically separate to make the whole thing more manageable you are
limited to a tiny number of models at silly prices.

David.

I checked, my AV amp (Sony STR-DG820) is a *receiver*!!

I never knew that!

Having looked at the rear of my TV i find no audio outputs at all, only
inputs, but there is an optical output, i am informed that this can
indeed be sent to a suitable Amp and the sound exited to speakers, just
to find a suitable amp now.

My TV similarly has no audio outputs, but I use the headphone out to spare
input (tape) on an aging receiver. I am sure this is not a "purist"
approach, but it seems to work well enough.
